Abstract：This study used the new sweet corn variety Jin Yin 131 as the test material,and conducted the annual cultivation experiment with 24 solar terms as the sowing time to explore the effect of annual sowing on its stage development.The results showed that sowing in the spring and autumn,which were the most suitable growing seasons,takes 5 days to seedling emergence,about 55 days to tassel and silk,and about 75 days to harvest.With the increase of average daily accumulated temperature,the development of each growth stage was advanced,and the harvest period could be advanced to 70 days;with the decrease of average daily accumulated temperature,each growth stage showed a delay,and the harvest period could be prolonged to about 120 days.There was a significant negative correlation between average daily accumulated temperature and the number of days for each stage of development.The study indicated that Jin Yin 131 sweet corn can be sown year-round,but its development at each stage was significantly affected by the average daily accumulated temperature.In production,it was recommended to sow in early spring and late autumn in the southeast fresh corn area to to fully leverage its high-quality and high-yield characteristics.
